Description
Technical field
The utility model relates to a kind of screwed flange erector, specifically a kind of screwed flange suspension type erector that is used for ultra-high pressure pipeline.
Background technology
In chemical plant installations was built, ultra-high pressure pipeline (being generally PN300MPa and PN150MPa) all adopted screwed flange to be connected, seal with metal lens ring.The accuracy of screw machining of super high pressure bend and flange is high, and tolerance fit is tight, and careless slightly when mounted flange and the pipe of just might causing " killed ".Super high pressure bend screwed flange weight is heavier, needs two people to cooperate a slice flange could be installed, and not only labour intensity is big, and if two people cooperate and badly very easily cause flange to fall to hurt sb.'s feelings or the screw thread of flange and pipe " is killed " accident.And the cost of a pipe will more than 10,000 dollar.In addition because the quantity of flange is a lot, if adopt pure manual method, not only speed influences the whole construction progress too slowly, and makes a fault easily and bring about great losses.
The super high pressure bend screwed flange mainly contains Dg50 and two kinds of workloads of Dg40 are big, the installation difficulty height, and its specification, size see the following form.
Flange nominal pressure (MPa) | Flange nominal diameter (mm) | Appearance and size (mm) external diameter * internal diameter * thickness | Flange net weight (kg) | Quantity (sheet) |
300 | ?Dg40 | ?295×88×60 | ?27 | ?366 |
300 | ?Dg50 | ?345×108×70 | ?40 | ?252 |
External at present this type of flange of installation mainly is to utilize a liftable hydraulic trolley, and two rollers are installed above.Earlier flange is placed on the roller, shift dolly onto pipe then before, regulate the height of flange by the lifting of hydraulic trolley, make pipe and flange concentric after, the promotion dolly forward, and with hand precession flange at leisure.Though this hydraulic pressure specific purpose tool is the labour intensity that can alleviate the installer, when using, there is following shortcoming in concrete job site:
A. it is too high to purchase a hydraulic trolley expense.
B. construction condition is different from the workshop, therefore uses hydraulic trolley to regulate flange and pipe concentricity and inconvenient at the scene.
Therefore, press for and a kind ofly can alleviate labor strength greatly, easy and simple to handle, guarantee the flange installation quality, finish the specific purpose tool of mounting flange smoothly.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of simple in structure, easy to make, applicability is strong, the low super high pressure bend screwed flange suspension type erector of operation labour intensity, to overcome the above-mentioned defective of prior art.
The technical scheme of the utility model technical solution problem is as follows:
A kind of super high pressure bend screwed flange suspension type erector is characterized in that, comprises horizontal suspension arm, lifting screw, is used to place the framework of flange; Described lifting screw vertically is provided with, and is threaded with the horizontal suspension arm; Described framework comprises framework cross-arm and movable frame, and the framework cross-arm is fixedlyed connected with the lifting screw lower end by connector; The other end of movable frame and framework cross-arm removably connects; Described movable frame is rotationally connected mutually by a plurality of connecting rods and forms, and the turning cylinder place of connecting rod is provided with rolling bearing.
The end that described framework cross-arm and movable frame removably connect is provided with groove, has contact with and draw ring with being fixed with on the connecting rod that groove fit on the framework cross-arm is connected.
Described movable frame is made up of structure identical front baffle and afterframe, and described front baffle and afterframe are respectively by the connecting rod structure in the form of a ring that is rotationally connected mutually, and the turning cylinder place at connecting rod between former and later two frameworks connects by rolling bearing is set.
By the technical scheme of above announcement as can be known, the utility model beneficial effect is as follows:
A. adopt suspension type to replace bracket type, solve the problem of on-the-spot Uneven road execution conditions difference.Simultaneously, replace hydraulic trolley, can significantly reduce expense with the suspension type erector.
B. replace the bracket type roller with rolling bearing, make it more light and flexible.
C. the lift action with screw rod replaces hydraulic lifting, has improved the precision and the degree of accuracy regulated.
The utlity model has advantages such as simple in structure, easy to make, cheap, that applicability is strong, labor strength is low, not only can use on ground, can also be used for the high-altitude and install, go for the installation of various different size flanges in addition by the size that changes connecting rod.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model;
Fig. 2 is a side-looking structural representation of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
As Fig. 1, the utility model super high pressure bend screwed flange suspension type erector comprises horizontal suspension arm 1, lifting screw 2, is used to place the framework 3 of flange; Described lifting screw 2 vertically is provided with, and is threaded with horizontal suspension arm 1; Described framework 3 comprises framework cross-arm 4 and movable frame 5, and framework cross-arm 4 is fixedlyed connected with lifting screw 2 lower ends by connector 6; Described movable frame 5 is rotationally connected with an end of framework cross-arm 4, and movable frame 5 removably connects with the other end of framework cross-arm 4; Described movable frame is rotationally connected mutually by a plurality of connecting rods 7 and forms, and turning cylinder 8 places of connecting rod are provided with rolling bearing 9.
